L

"Figure 8 is ay detailsection taken onV the line 8 8 of Figure '1. v v The tender underframe may be of any desired form but we illustrate a preferred frameV of vthe type` in which the bottom of the frame forms the bottom of the tank whereby the capacity of the tender is increased andthe center of gravity is lowered. This type of framefis disclosed in Patent No. 1,663,036, issued March 20, 1928, to Ashe 8:

Piiage'r and includes spaced center' sills 1, side sills 2, a bottom web 3, transverse members 4; an end sill v5 and-other elements referred to below. VThe superstructure side sheets 6 are secured di reetly to the side sills 2 of the underframe and the forward part of the tender is provided with a centrally located Yfuel compartment, the sides of which are formedby plates 4'l and 8 and the bottom'of which isfiorlnedv by elements of our Y stolrer trough device.

The trough includes sides 9 which are vertical in their upper portion and converge downwardly, merging `in an arcuate portion l0 whieh'receives the lower half oythe' conveyor screw 11. Lat-..

veral extensions 12are preferably formedjintegrally -with the upper parts of the trough sides 9 and are provided with anges 13 at their outer edges to which lower edges of'sheets 7 are ser cured. vThese extensions 12 are rabbeted, as indicated at 14, to provide surfaces mounting the cover"plates"15` and guide strip 16. The outer edges 'ofy extensions 12 are braced from the body of the trough by inclined elements 17. 'At the opposite ends 'ol the trough are lateral extensions,

that at the 'forward end-including a rear wall y23 and side walls 24 having flanges 25 for mounting the 'tankend sheets l26. These parts form means for walling ofi the space over the draw bar pocket 27,- which space should be open tothe atmosphere to permit manipulation oidrawbar elements. f i

y The lateral extension at the `rear oi the trough comprises an `end wall 20 with sides '28 forat- `tachment of the fuel compartment plates 'i andl including iianges 23a forming a pan-like chamber'ior receiving the conveyor screwI gearing G. The rear' wall 20 also includes an integral bearing bracket 18 vfor lmounting the conveyor; screw A rectangular Yframe 29 projects fromV the lower portion Vofwall' 20 and isfadapted to surround the upper end oiianl opening [30' provided in the tender frame to permit manual Vaccess to the'rear of the Stoker device and to the gearing G. This Y,

frame` serves to attach the adjacent edges of the' fuel compartment sheetss'iand A removabl cover plateBl is appliedto chamber 28a. y

' The trough is supported by wallsZO and 23 and by arr intermediate memberli). Walls 20 and 23 i are wide enough to span the space between the frame center sills 1 and rest upon-the latter as Awell as upon transverse members 4 of the underframe. Member 19 ris of restricted width and is supported directly upon that portion 4of theframe cross member 4f" which extends between the cenice 2. In aV deviceof'the classdescribed, Aatrough f walls 23 and 20 and preferably is welded to the same, as indicated at W, bracing the wall 23, and

wall 20 and forming a housingfor driveshaft 34 and excluding water from the same and from f the shaft bearings 33y and 3 5. Y The forward portion of the structuremounts a casing 38 adapted to enclose the rearl end` of the forward conveyor unit (not shown) which extends from the tender to the locomotive re box. A crusher member 39A is mounted on the interior of thevforward vend of the. housing and cooperates withjthe screw` 11 to breakup the coal inthe usual manner. Members 33- and 39 may be'formed integrally'with `the housing` but [we prefer to form them separately so that access to the universal joint may be had readily and so that the', crusher unit may be replaced fromtime to time.. k` i By forming the parts describedV in a single unit, preferably consisting substantially of a one piece casting, the structure is so rigid that there be vpractically no, play between the shaft bearings and we can utilize asingle pieceof shaftingj extending throughout the' lengthof the Stoker mechanism contained inthe tender; VThis eliminates the vnecessity of; `additi on al intermediate bearingsand the provisionsof a flexible .joint intermediate the ends of the conveyor screw such as usually provided in Stoker mechanisms.

.l The described structure also, y forms a water tight cover for thejwater compartment below it,

or-a bottoml for the fuel 'compartment aboveit. Its use will reducethe watercapacity of the 'tender a relatively slight :amountand,.thej effectiveness of thegtender is increased vaccordingly.
